Came to post this. I don't remember one bug or glitch in many a playthrough. The Dead or Alive series generally works a treat.
Metal Gear Solid 2 was near perfect on PS2, as I recall. I say "near" because of the very occasional frame rate drops. Other than that, the rest of that game seemed to be smoother than James Bond on butter. The level of detail was astounding too.
